FAUCET.

Application filed June 8, 1921. Serial No. 475,851.

To all whom it may concern:

Be it known that I, liliroHELL W. RUssnLL, a citizen of the United States of America, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented a new and useful Faucet, of which the following is a specification.

My invention relates to improvements in faucets, and more particularly to the valve constructions of the same or the operating means for the valves therein, and consists of a cam member or members on the inside of the barrel of the casing, an enlargement or collar on the valve-stem, in which collar is a recess or recesses to receive said cam members, and having cam surfaces to cooperate with or ride on said members, and a spring arranged to retain the cam surfaces of the, recesses in contact with the cam members, together with the other necessary parts and members, all as hereinafter set forth.

The primary object of my invention is to provide a spring-actuated valve in a faucet, which valve is normally retained iii closed position by its spring, with means for opening said valve against said spring, and wherewith quick action is obtained in both the closing and opening operations. lVith my construction the danger of the accidental opening of the valve is practically eliminated. This is due to the fact that the spring always has a tendency to close the valve and to retain it in closed position. The valve can be opened only by manual rotation of the valve-stem in the direction necessary to actuate the same upwardly or downwardly, through the medium of the cam members, and against the force of the sprlng.

Another object is to provide means of this character which is very simple and inexpensive in construction, yet strong and. durable, and highly efficient.

Other objects and advantages will appear in the course of the following description.

I attain the objects and secure the advantages of my invention by the means illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a faucet which embodies a practical form of my invention, a portion of the casing being broken out to disclose the valve and valve mechanism, and portions of the latter being in section; Fig. 2, a top plan and section through the barrel of the casing, taken on lines 2-2,

1n F 1g. 1; 1* 1g. 3, a side elevation of the valve-stem and its integral parts; Fig. A

a cross section throu 'h the valve-stem enlargement or collar, on lines 4 1-, Fig. 3; Fig. 5, a fragmentary detail in elevation of one of the cam lugs, and, 6, a fragmentary detail in top plan of said lug.

Similar reference characters designate 8, of which. the nut 10 forms a part. A

spring 11 is also represented. At the bottom of the valvestem 8 is a valve 12 having secured to the under side thereof, by means of a screw 13, a valve disk 1 1. I When the valve-stem 8' is actuated downwardly,

the disk 14 is forced against the valve-seat 6 and closes the opening surrounded by the same. These parts and members are all old and of usual and well-known construction.

On the inside of the barrel 7 at diametrically opposite points are two interiorly-arcuate integral cam lugs 15. Each of these lugs has an inclined upper edge 16 which forms a cam surface. The inclinations of the two cam surfaces 16 are in opposite directions.

The valve-stem 8 is provided above the valve 12 with a collar 17. In the periphery of the collar 17, at diametrically opposite points are two recesses 18, each of which has an upper inclined edge 19 which forms a cam surface. The cam surfaces 19 extend in opposite directions, and their inclinations and directions correspond with the inclinations and directions of the cam surfaces 16 of the lugs 15. recesses 18, entering said recesses at the bottom when the valve-stem 8 is placed in position in the barrel 7.

The recesses 18 are large enough to afford, within the limits fixed thereby, the necessary amount of rotation to the valve-stem 8 to open and close the passage surrounded by the valve-seat 6, before being stopped by the lugs 15 which are in said recesses, coming in contact with the long walls at one end of said recesses. When the parts are assembled the cam surfaces 19 rest and ride on The casing 1 includes the usual 70 The lugs 15 are receivable in the 100 the cam surfaces 16, so that the collar 17 and with it the valve-stein 8 and the valve 12 is raised or lowered according to the direction of rotation of said collar. As here arranged, when the valve-stem 8 is turned to the left the collar and valve are elevated against the force of the spring 11, and when said stem is turned to the right said collar and valve are depressed. Upon merely releasing the valve-stem it is actuated to close the valve-by the force of the spring. Thus it is seen that the spring 11 normally closes and retains the valve in closed position, with the disk 1% on the valve-seat 6, the cam surfaces 19 and 16 facilitating or in any event permitting the automatic closing operation or action.

It is preferable to employ two cam lugs 15 and the same number of cam-surface recesses 18, because of the balanced and easier or smoother action that results, as compared with the action resulting from the use of a single lug and a single cam-surface 19.

I am aware that various kinds of helical screw and cam devices have previously been employed in faucet construction, and do not, therefore, seek to claim the same broadly.

This faucet is particularly useful as a safety valve for hot-water heaters, waterfronts for stoves and ranges, and the like, to relieve excessive pressure in the event the pipes or water containers become overheated, and thus prevent the bursting or rupture of the same.

What I do claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, in a faucet, with a casing provided with a valve-seat and with an interiorly-arcuate integral lug, said lug having on its upper edge an inclined cam surface, of a valve-stem provided with a valve to open and close the passage surrounded by said valve-seat, and further provided with.

-a collar, said collar having a recess in one side thereof to receive said lug, the upper edge of which recess forms an inclined cam surface to ride on the cam surface of said lug, the latter being concentric with said collar, and the long wall at one end of said recess cooperating with the adjacent end of said lug to limit the rotary movement in one direction of the parts, and a spring arranged to force said valve toward said seat. 2. The combination, in a faucet, with a case provided with a valve-seat and with 0ppositely-disposed interiorly-arcuate integral lugs having on their upper edges cam surfaces inclined in opposite directions, of a valve-stem provided with a valve to open and close the passage surrounded by said valve-seat, and further provided with a collar having in opposite sides thereof recesses to receive said lugs, the upper edges of said recesses forming inclined cam surfaces arranged and adapted to ride on said firstnamed cam surfaces when said valve-stem is rotated, and the long walls atone end of said recesses cooperating with adjacent ends of said lugs to limit the'rotary movement of the parts, and a spring bearing on said collar to force the same with its parts in the direction to cause said valve to close said valveseat.
